[0048] After the position of the resisting rod 4251 and the opening of the hook ring 422 are limited and fixed, the resisting rod 4251 can be pushed at the same time, so that the resisting rod 4251 drives the extrusion block 42555 to move on the extrusion rod 42553, and at the same time, the extrusion block 42555 squeezes the connecting spring 42556, so that the resisting rod 4251 can move toward the inside of the hook ring 422, thereby facilitating the removal of the auxiliary cable;

[0049] Please refer to Figure 1-9 The sliding assembly 426 includes two sliding frames 4261 fixedly connected with the sides of the shackle 422, the side of the sliding frame 4261 is provided with a sliding groove 4262, the inner side of the sliding groove 4262 is fixedly connected with a sliding rod 4264, the side of the sliding frame 4261 is fixedly connected with a magnetic block 4263, the side of the sliding rod 4264 is slidably connected with a sliding block 4265, the side of the sliding block 4265 is slidably connected with the inner side of the sliding groove 4262, the side of the sliding block 4265 is fixedly connected with a circular plate 4266, and the side, away from the sliding block 4265, of the circular plate 4266 is fixedly connected with a limiting sleeve 4267;

[0051] Specific working process:

[0052] The bridge-type metallurgical hoisting equipment moves the hook to the specified position in the three-dimensional space through the coordinated action of the cart running mechanism and the trolley running mechanism;

[0053] When lifting heavy objects is needed, the operator starts the hoisting component 3 through the electrical control system, the motor drives the drum to rotate, the steel wire is wound on the drum, the hook component 4 is lifted, and the heavy object is lifted;

[0054] Then, the heavy object is transported to the required position through the running of the cart and the trolley, and the heavy object is lowered through the hoisting component 3;

[0055] During the whole process, the electrical control system accurately controls each mechanism according to the instructions of the operator and the running state of the equipment, to ensure the safety and efficiency of the hoisting operation;

[0056] By starting the hoisting component 3, the motor drives the drum to rotate, the steel wire is wound on the drum, the steel wire drives the hook mechanism 42 to move upward through the pulley mechanism 41, the shackle 422 is gradually stressed, and the heavy object is stably lifted;

[0057] When hoisting the goods, the auxiliary steel cable for hoisting the goods enters the shackle 422 through the opening of the shackle 422, moves in the placing groove 427 through the sliding stop assembly 425, so that the stop assembly 425 can abut the opening of the shackle 422, and the position of the stop assembly 425 is limited and fixed by the sliding assembly 426, so that the stop assembly 425 closes the opening of the shackle 422 to prevent the auxiliary steel cable from coming out, and the placing plate 424 is arranged on the inner side of the shackle 422, a plurality of placing grooves 427 are formed in the placing plate 424, and the material of the placing plate 424 is rubber material, so that the auxiliary steel cable for hoisting the goods placed in the shackle 422 can increase the contact friction between the auxiliary steel cable and the placing plate 424, thereby ensuring the stability of the material during hoisting;

[0058] The auxiliary steel cable is placed in the shackle 422 through the opening of the shackle 422, so that the auxiliary steel cable abuts the placing plate 424, and the circular plate 4266 is pushed, so that the circular plate 4266 drives the connecting shaft 4253 to move in the moving groove 423 through the sliding block 4265, so that the connecting shaft 4253 drives the stop rod 4251 to abut the opening of the shackle 422, and the position of the stop rod 4251 is limited and fixed by adjusting the limiting sleeve 4267.

[0059] When the connecting shaft 4253 drives the stop rod 4251 to abut the opening of the shackle 422, the limiting block 42671 is rotated, so that the limiting block 42671 drives the threaded rod 42672 to move in the inner side of the circular plate 4266 and the sliding block 4265 in a threaded manner, so that the threaded rod 42672 abuts the sliding rod 4264, thereby fixing the position of the sliding block 4265, and further avoiding the phenomenon that the position of the stop rod 4251 in the opening of the shackle 422 deviates;

[0060] The threaded movement of the threaded rod 42672 driven by the rotating limiting block 42671 can realize accurate adjustment and locking of the position of the sliding block 4265, and the operator can accurately determine the abutting degree of the threaded rod 42672 and the sliding rod 4264 by accurately controlling the rotation angle of the limiting block 42671 according to actual needs, so as to fix the sliding block 4265 at the required accurate position, ensure the cooperation accuracy of the stop rod 4251 and the opening of the shackle 422, and meet the requirements of different hoisting operations on position accuracy;

[0061] After the position of the resisting rod 4251 and the opening of the hook ring 422 are limited and fixed, the resisting rod 4251 can be pushed at the same time, so that the resisting rod 4251 drives the extrusion block 42555 to move on the extrusion rod 42553, and at the same time, the extrusion block 42555 squeezes the connecting spring 42556, so that the resisting rod 4251 can move toward the inside of the hook ring 422, thereby facilitating the removal of the auxiliary cable;

[0062] During the hoisting operation, if it is found that the position of the auxiliary steel cable needs to be temporarily adjusted, or the situation inside the hook ring 422 needs to be checked, the operation can be conveniently performed by pushing the blocking rod 4251 without completely releasing the limit fixation. This ensures the continuity and safety of the hoisting operation to a certain extent and avoids the safety hazards caused by frequent disassembly and fixation.

[0063] After the cargo is hoisted to a suitable position, when disassembly work is required, the limiting kit 4267 can be rotated to release the limiting kit 4267 from the position between the slider 4265 and the slide bar 4264, thereby pushing the circular plate 4266, which drives the connecting shaft 4253 to move in the moving groove 423 through the slider 4265 until the side surface of the slider 4265 is against the inner side of the magnetic block 4263, thereby magnetically fixing the position of the slider 4265 and making the blocking rod 4251 disengage from the opening of the hook ring 422, so that when the auxiliary steel cable on the hook ring 422 is unloaded, the blocking rod 4251 is prevented from interfering with the normal unloading work;

[0064] When the side of the slider 4265 abuts against the inner side of the magnetic block 4263, the magnetic force is used to fix the slider 4265, which can achieve accurate positioning of the position, ensuring that the blocking rod 4251 is accurately separated from the opening of the hook ring 422, thereby avoiding unloading difficulties or other problems that may be caused by inaccurate positioning;

[0065] The magnetic fixation ensures that the slider 4265 does not move randomly during the unloading process to a certain extent, and maintains the blocking rod 4251 in a state of being separated from the opening of the hook ring 422, providing a stable condition for the unloading operation and reducing the possibility of interference with unloading due to accidental resetting of the blocking rod 4251;

[0066] This design of adjusting the position of the resistance rod 4251 by rotating, pushing and other operations allows the equipment to maintain good adaptability in different unloading scenarios and cargo types. Whether it is the lifting and disassembly of small or large cargo, it can be completed through corresponding operations, which improves the versatility of the equipment.

[0067] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
